============
docformatter

Formats docstrings to follow PEP 257_.

.. _PEP 257: http://www.python.org/dev/peps/pep-0257/

Features

docformatter automatically formats docstrings to follow a subset of the PEP
257 conventions. Below are the relevant items quoted from PEP 257.

For consistency, always use triple double quotes around docstrings.
Triple quotes are used even though the string fits on one line.
Multi-line docstrings consist of a summary line just like a one-line
docstring, followed by a blank line, followed by a more elaborate
description.
Unless the entire docstring fits on a line, place the closing quotes
on a line by themselves.

docformatter also handles some of the PEP 8 conventions.

Don't write string literals that rely on significant trailing
whitespace. Such trailing whitespace is visually indistinguishable
and some editors (or more recently, reindent.py) will trim them.

docformatter formats docstrings compatible with black when passed the
--black option.

docformatter formats field lists that use Epytext or Sphinx styles.

See the the full documentation at read-the-docs, especially the
requirements section for a more detailed discussion of PEP 257 and other
requirements.

Installation

From pip::

$ pip install --upgrade docformatter

Or, if you want to use pyproject.toml to configure docformatter and you're using
Python < 3.11::

$ pip install --upgrade docformatter[tomli]

With Python >=3.11, tomllib from the standard library is used.

Or, if you want to use a release candidate (or any other tag)::

$ pip install git+https://github.com/PyCQA/docformatter.git@<RC_TAG>

Where is the release candidate tag you'd like to install. Release
candidate tags will have the format v1.6.0-rc1 Release candidates will also be
made available as a Github Release.

Example

After running::

$ docformatter --in-place example.py

this code

.. code-block:: python

"""   Here are some examples.

    This module docstring should be dedented."""


def launch_rocket():
    """Launch
the
rocket. Go colonize space."""


def factorial(x):
    '''

    Return x factorial.

    This uses math.factorial.

    '''
    import math
    return math.factorial(x)


def print_factorial(x):
    """Print x factorial"""
    print(factorial(x))


def main():
    """Main
    function"""
    print_factorial(5)
    if factorial(10):
        launch_rocket()

gets formatted into this

.. code-block:: python

"""Here are some examples.

This module docstring should be dedented.
"""


def launch_rocket():
    """Launch the rocket.

    Go colonize space.
    """


def factorial(x):
    """Return x factorial.

    This uses math.factorial.
    """
    import math
    return math.factorial(x)


def print_factorial(x):
    """Print x factorial."""
    print(factorial(x))


def main():
    """Main function."""
    print_factorial(5)
    if factorial(10):
        launch_rocket()
